Specication of Letters Patent. Patented Sept?. K5,

Application filed Hatch 8, 1913. Itie-rial No. 752,884.11.

To alt whom it may concern.: Be it known that I, AXEL MALM, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Manifolding Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

lhis invention relates to new and useful improvements in manifolding devices, and the principal object of the invention is to provide a feeding device for webs of paper which will successfully feed lengths of webs to a position where they may be readily severed, without the employment of a carriage for said webs as is common in similar devices now in general use.

Another important object of the invention is to provide an operating means for the feeding device and to provide means for controlling the operating means whereby the feeding device will be regulated so as to successively project uniform lengths of said webs beyond the feeding device.

A further object of the invention is to lprovide a feeding device including a pair of feed rollers for the webs, and to provide means for intermittently rotating the rollers a predetermined number of times.

A still further object of the invention is to provide a novel means for shifting and positively locking one of the feedl rollers in spaced relation to the other roller to permit the webs being readily passed there-between.

In the accompanying drawings Figure 1 is a partial top plan view of a register showing the application of one embodiment of my invention, Fig. 2 is a detaillongitudinal sectional view tliere-througli, Fig. 3 is a detail view showing the ratchet connection between one of the feed rollers and the operating means, Fig. 4 is a detail sectionalview showing the locking pawl for the feed roller, and Fig. 5 is a detail sectional view showing the means for shifting and locking one of the feedrollers in spaced relation to the other roller.

In these drawings I have illustrated one embodiment of my invention and have shown same as comprising a casing A of ordinary construction including side Walls 5-5. Centrally supported by these walls is a table 6 which in this instance is detachably supported to permit of ready access to ;the interior of the casing. The webs of paper are drawn olf paper rolls which are journaled within the casing, and thse webs fire carried over the table (3 in a manner similar to other machines of this type now in general ilse. These webs are printed with bills, the lengths of to suit the work of diderent offices. I have, therefore` provided a feeding means for these webs by means of which Webs of predetermined lengths niay be successively and intermittently projected to a position where they may be severed. Itl will, of course, be ,understood that as many webs may be employed as desired, and that these webs are Idisposed one upon the other, and Carbon sheets disposed intermediate adjacent webs. To this end I have provided a pair of feed rollers 7 and 8. These rollers are disposed .transversely of the casing and adjacent the tend of the table opposite the end over which the paper webs are fed. The lower roller, lor feed roller 7, is loosely mounted upon a power shaft 9 which is journaled in suitable bearings formed in the walls 5 ofthe casing. Fixed on one end of the roller 7 is a ratchet wheel 10, and lixed on the shaft 9 between 1s a gear wheel 11 which carries springpressed pawls 12-12 for engagement with lthe teeth of theratchet wheel 10. It will thus be observed that( upon rotation of the will rotate therewith, and through the medium of the pawls 12 and 'ratchet wheel 10, the roller 7 will be' rotated in the same direction, but upon the reverse rotation of the shaft 9 thel pawls 12 will slide over the ratchet wheel 10 and thereby prevent the 4roller 7 from being reversed. In order to effectively lock the roller 7 against this reverse movement,y and yet permit of the roller having a forward movement, I have provided a pivoted spring actuated locking detent 13, said detent being mounted upon the other wall 5 of the casing and coperating with a gear wheel 14 that is fixed on that end of the roller 7.

The upper roller 8 constitutes a pressure roller and is provided with trunnions 15 which operate in vertical slots 16 formed in brackets 17 carried by the side walls 5. Formed in each bracket 17 directly above at its upper end by a threaded plug 19.

yshaft 9 in one direction the gear wheel 11v these bills varying the ratchet wheel and the adjacent wall 5 erv the slot 16 is an opening 18 which isl closed bearing shoe 20, 'and this shoe is" preed downwardl by means -of a coil-spring 21 which is isposed within the opening 18 between the plug 19 and shoe 20. The

ward y for frlctlonal engagement w1th the roller 7 to permitY the webs of paper being fed therethrough upon rotation of the roller T\in the proper direction. f This movement is' imparted to the'feeding means by a handcrank `22vwhich isfixcdon-one end of1 the shaft 9.

' In order to facilitate the initial insertion of the paper webs between the feed rollers, the rollers are movedapart, and' in order to so space these rollers l have provided a means for shiftin the ressure roller 8 away from the-f roller 4and to lock said pressure roller in its spaced relation. To this end I have journaleda cam shaft 23 in th'e .walls 5:oftho 'cas' below` the feed roller 7, and fixed to this aft ad'acent eaeh end thereof isa cam finger' 24.' ach finger 24 operatesfin a recess formed in the respectiveL side wall 5, onevof said fingers being disosed between the gear wheel 11 and the ad- ]acent wall 5', and theother finger being dis-l posed between the gear wheel 14 and the other wall 5. Each finger is centrally formed with an arcuate slot 25 through which the shaft 9 extends, this slot rm1tting the fingers to have a limited oscillatory l movement. The upper edge of each finger is formed with aA cam face 26 and a seat'27, the-cam face 26 being disposed directly below andin operative'relation to the trunnionsl of the pressure roller 8. When the cam iingers`24 are shifted to the right the pressure roller '8 will-v be' raised 'against the tensions of the springs 21,"ai1d Aupon the complete' movement o the cam lingers 24 the trunnionsl 15 will bedisposed upon the seats 27. In order to rock t e shaft 23 and thereby actuate 'the cam ngers 24,' said shaft'y 23 is provided'with a finger lever 28, and .in order to assist'the fingers in return` ing to their'ncrmal or'inoperative positions I have' rovided aspring 29 which is coiled about e shaft 23 and has one end fixed thereto, the'other end being fixed to the ad` jacent side wall of the casing.

As before 'stated it is desired to control the feeding means so that uniform lengths of the paper webs may besuccessively (projected eyond the feeding means, an in order to accom lish this function I have provided a racE-bar 30 which is slidably mounted u on the side wall 5 ad'acent the gear whee 11. This rack-bar 1s formed with an elongated longitudinal slot 31 throughx which supporting pins 32 ass and are secured to the casing.' Rotata ly supported by the adjacent side wall is a coinservefto, press the roller 8 down'.-v

1 4 ing means,

pound gear, the pinion 33 thereof meshing with the teeth o therack-bar 30 and the `eai"'3-1 thefeof 'meshing with'the intermediate' gear 35, the latter in turn meshing Awith. the gear wheel 11. It will thus be ob- `served that upon rotation of the shaft I9 in one direction the 'rack-bar 30 will be shifted, and that the continuous movement of the shaftiwiil'be limited by the amount of the sliding movement of said rack-bar. The sliding movement of the rack-bar 30 is regulated in accordance withfthe lengths of the paper webs to be projected beyond the feed- V and to adjust the movement of the rack-bar to suit various lengths of webs, I have# provided a stop-pin 36 -which is adaptedto-proj'eot throughr any one of a ,number Ofbpenings 37 formed within the side wall. These openings are dis din alinement with the rack-bar 30 so t at said bar will engage' the pin in any one of its lpositions andthereby limit the rotation of the feed roller 7 in one direction. -When these machines are adjusted at the factory preferably only one opening 37 for the stop-pin 36 is formed in t e casing, the position of this opening being determined y the length of the bill used by the purchaser of t e device. It will, of course, be `understood that more` than one opening'' may be formed at the time the device is built so as to accommodate the same to bills of different lengths` In operation after the several webs of paper have been clamped between the rollers 7 and 8, the crank handle 22 is rotated in :i .forward direction. The rotation of this -handle causes the rack-bar 30 to move toward the stop-pin 36. Therefore, as soon as the bar engages said stop-pin the movement.

.of the crank-handle 22 will be arrested. 4By 'this time the proper length of aper webs ,have` been projectedy beyond t e feeding `means and are in a position to be readily severed. The handle-crank 22 is then rotated in a clock-wise direction or in a direction toward the table 6. As the shaft 9 is thus rotated the pawls 12 will yride over the' teeth of the ratchet 'wheel 10 as above noted, and the feed roller 7 will be held against rotary movement by the locking detent 18. The crank handle is rotated in this direction until the rear end of the slot 31 engages the pin 32 which checks the return movement o the'rack. The crank handle A22 is again rotated in a forward direction and as a result the next length of web is projected beyond the feeding means. By this construction uniform lengths of webs ma be intermittently and successively projec and by adjusting theI sto -pin 36 the machines may be employed or bills of differ- 'ent lengths as will be readily understood.

VWhi e I haveV shown and described one embodiment of my invention it will be understood that this has been chosen for the purposes of illustration only andthat I do not desire to be limited to the details of construction shown and described, for obvious modifications'will occur to a person skilled in the art.
